Therefore, with this approach it is possible to obtain films with different monomers on double layer or composites, with organic/inorganic materials or particles and use them on sample pretreatment for chemical analysis.
The four goals of plasma sample pretreatment for HPLC MS analysis, i.e. removal of proteins, removal of other low-molecular interferences, preconcentration of the analytes of interest, and matching the sample solvent with the HPLC MS system, can be rapidly performed in a very simple step by using the SIPTE method.
Sample pretreatment for the commercial ELISA kit was performed according to the manufacturer's instructions.
Sample preparation includes protein removal and metabolite extraction (see section " Sample pretreatment for mass-spectrometry analysis ").
An individual SOP for the sample pretreatment for mass-spectrometry analysis is recommended, because this pre-analytical step is not performed at once, e.g. in the clinic, but in the laboratory of the analytical (bio chemists.
In general, sample pretreatment for mass-spectrometry analysis is the least critical pre-analytical step because it is performed by analytical experts and can be highly standardized, in contrast with, e.g., blood drawing under highly variable clinical conditions.
Keeping the sample pretreatment for mass-spectrometry metabolomics analysis as simple as possible guarantees the highest reproducibility.
Thus, this method shows excellent prospects for sample pretreatment and analysis of FQs in human body fluids.
Many disadvantages of using the HPLC, CE, GC-MS, and TLC analyses in general are (i) the long time needed for sample pretreatment and analysis, (ii) the requirement of using organic solvents of high quality, which is quite expensive, and (iii) the disposal of the used organic solvents has to be taken into consideration.
Dispersive liquid liquid microextraction (DLLME) has been used as a simple and efficient sample pretreatment method for the analysis of OTA in wines, being optimised by means of experimental design.
Crude cell suspensions could be used with minimal sample pretreatment, allowing fast analysis.
